Description
Technical field
The utility model relates to a kind of technique device that ice and snow is stuck in the railway road that melts, and particularly relates to a kind of device of thawing ice and snow on railway turnout.
Background technology
Railway road fork often freezes fork in winter or snowy day, causes locking not tight, influences the normal operation of railway, and for preventing that because of accumulated snow freezes fork now main dependence is snow removing or the snow removing of brushing Snow Agent manually, its labour intensity is big, work under bad environment.Waste of manpower and be difficult to guarantee operating personnel's safety problem for a change manually removes the snow, developed the snow-removing device of some mechanical coverage modes in recent years, but because of its complex structure, the sensitivity level of action and reliability can not satisfy actual instructions for use, are difficult to promote the use of.Now also there are some railway road forks to adopt mode of heating to melt the technology of road fork ice and snow, as the heating road fork equipment of Beijing West Railway Station from external introduction, a kind of railway road fork snow removing defroster of being provided in the publication number CN2407033 application number 00204316.5 utility model title " railway road fork snow removing defroster " of 2000.11.22 bulletin of Patent Office of the People's Republic of China and for example utilizes the method for heating wire heating.Though adopt the method for heating can reach the effect of snow removing, existing mode of heating programming rate is slow, energy consumption is big, is difficult to realize automatic control.
The utility model content
The purpose of this utility model is to solve the defective that exists in the prior art, provides a kind of speed that thaws ice and snow fast, environment is not had the device of the thawing ice and snow on railway turnout of pollution.
For this reason, the utility model provides a kind of device of thawing ice and snow on railway turnout, comprise slide plate of switch tongue, slide plate of switch tongue chassis, road fork rail, the device that the utility model provides is a magnetic field induction eddy current heater coil, and described magnetic field induction eddy current heater coil links to each other with the magnetic field induction current feedback circuit; After the magnetic field induction current feedback circuit is connected power supply, the magnetic line of force that magnetic field induction eddy current heater coil produces passes the slide plate of switch tongue of railway road fork, the ferrous material in the slide plate of switch tongue chassis, the ferrous material that the eddy current heating railway road that forms is stuck rises the ferrous material temperature rapidly and melts the ice and snow that the road is stuck.The heating principle that this device adopted is that the induced-current that the magnetic field induction current feedback circuit produces produces magnetic field by the magnetic field induction eddy current coil, when the magnetic line of force in magnetic field passes through ferrous material, can produce countless little eddy current, make ferrous material itself from the scanning frequency heating, thereby melt contacted with it ice and snow fast.The heater that adopts magnetic field induction eddy current heating principle to make, when freeze ferrous material that fork the time opens slide plate of switch tongue that device makes railway road fork, slide plate of switch tongue chassis the magnetic line of force in magnetic field by the time self-heating fast, because slide plate, the slide plate of switch tongue chassis of road fork are to rely on self-heating, rather than will transmit by the mode of conduction from the heat that other electro-heat equipment produces, temperature rises fast, thermal efficiency height, thus can reach the effect that ice and snow is stuck in quick thawing road.Make slide plate of switch tongue and slide plate of switch tongue chassis Fast Heating by this device, melt on slide plate of switch tongue and the slide plate of switch tongue chassis and between ice and snow, keep can moving mutually between slide plate of switch tongue and the slide plate of switch tongue chassis.Described magnetic field induction eddy current heater coil is embedded in the inside, slide plate of switch tongue chassis or is installed in next door, slide plate of switch tongue chassis; Equally also described magnetic field induction eddy current heater coil can be embedded in the slide plate of switch tongue the inside or be installed in the slide plate of switch tongue next door; Perhaps simultaneously described magnetic field induction eddy current heater coil is embedded in slide plate of switch tongue and slide plate of switch tongue chassis the inside, perhaps is installed in next door, slide plate of switch tongue and road fork chassis simultaneously, the speed of heating is further accelerated.
In the device of the another kind of thawing ice and snow on railway turnout that the utility model provides, on the described magnetic field induction current feedback circuit temperature controller is installed, can accurately control the temperature of pitching by temperature controller, improve the efficiency of heating surface.
In the device of the another kind of thawing ice and snow on railway turnout that the utility model provides, mounting temperature sensor on the described slide plate of switch tongue chassis, temperature pick up links to each other with temperature controller; By temperature pick up, can monitor the temperature of fork at any time, by temperature pick up and temperature controller, can realize automatic control.Temperature pick up can certainly be installed on the described slide plate of switch tongue.
In the device of the another kind of thawing ice and snow on railway turnout that the utility model provides, described magnetic field induction eddy current heater coil is to be made of a plurality of independent rectangle magnetic field induction eddy current heater coils, each rectangle magnetic field induction eddy current heater coil all links to each other with the magnetic field induction current feedback circuit individually, can independently use.Because railway road fork is related to the safety of the people's lives and property, if have only a coil, will cause tremendous loss just in case be damaged, in order to improve security reliability, now magnetic field induction eddy current heater coil is adopted a plurality of independent compound modes, even producing, part wherein damages, remaining heater coil in the same old way can operate as normal, if the power with coil remains with certain leeway in advance, even a part is wherein damaged the safety that remaining heater coil still can guarantee railway road fork, part is wherein damaged the normal use that does not influence railway road fork, for maintenance and repair try to gain time precious to one.
The device of a kind of thawing ice and snow on railway turnout provided by the utility model is compared with the technology of existing thawing road fork ice and snow, has following advantage:
1. thawing speed is fast: the technology of existing thawing railway road fork is the temperature rising with whole road fork, the ice and snow that generally needs long-time heating the road could be stuck melts fully, and the utility model is by making the fork self-heating, electrothermal calefactive rate is fast, only needs a few minutes just ice and snow can be melted fully;
2. environmentally safe: with spill salt and compare environmental nonpollution;
3. thermal efficiency height: adopt magnetic field induction eddy current heating principle, the thermal efficiency is more than a times of traditional heating method.
